关于荧光标记的，翻译成英文

异硫氰酸荧光素 (fluorescein isothiocyanate, FITC)纯品为黄色或橙黄色结晶粉末，易溶于水和酒精溶剂。有两种异构体，其中异构体Ⅰ型在效率、稳定性与蛋白质结合力等方面都更优良。FITC分子量为389.4，最大吸收光波长为490～495nm，最大发射光波长为520～530nm，呈现明亮的黄绿色荧光。FITC在冷暗干燥处可保存多年，是目前应用最广泛的荧光素。其主要优点是人眼对黄绿色较为敏感，通常切片标本中的绿色荧光少于红色。用FITC标记的各种抗体]，多肽，多糖]等物质已广泛用于各种生物研究。

FITC有两种同分异构体，其中异构体A在效率、稳定性、与蛋白质结合能力等方面都更好，在冷暗，干燥处可保存多年，另外由于人眼对黄绿色较为敏感，通常切片标本中的绿色荧光少于红色，所以FITC成为使用最广泛的荧光素。用FITC标记的各种抗体，多肽，多糖等物质已广泛用于各种生物研究。
近年来对于药物载体的研究，也常使用荧光物质。将荧光物质引入药物载体的方法有：（1）通过化学结合的方法使荧光物质与聚合物耦联，再将耦联后的聚合物制备成载药微粒或者直接将荧光物质耦联在制备好的微粒表面。（2）直接将荧光物质或标记的药物包载进纳米颗粒。

你们这些全是用翻译软件翻译出来的，那样我也会，我希望是真的用心翻译的。。

FITC (fluorescein isothiocyanate, FITC) pure yellow or orange yellow crystalline powder, soluble in water and alcohol solvent. There are two isomers, one isomer type Ⅰ efficiency, stability and protein binding, etc. are better. FITC molecular weight of 389.4, the maximum absorption wavelength for the 490 ~ 495nm, the maximum emission wavelength for the 520 ~ 530nm, a bright yellow-green fluorescence. FITC in the dark cold can be stored dry for many years, is currently the most widely used fluorescein. Its main advantage is the human eye is more sensitive to yellow-green, usually biopsy samples less than the green fluorescent red.
FITC labeled with various antibodies], peptide, polysaccharide] and other substances have been used in a wide variety of biological research.
FITC, there are two isomers, one isomer A in terms of efficiency, stability, and protein binding capacity, etc. are better in the cold dark, dry place can be stored for many years, the other as a result of the human eye is more sensitive to yellow-green, biopsy specimens are usually in the red than green fluorescence, FITC therefore become the most widely used fluorescein. FITC labeled with a variety of antibodies, peptides, polysaccharides and other substances has been widely used in a variety of biological research.
In recent years the study of drug carrier, and is often the use of fluorescent substances. The introduction of the fluorescent material of drug delivery methods are: (1) by chemical method combined with fluorescent material so that coupled with the polymer and then coupling of the polymer after the drug-loaded particles prepared or coupled directly to the fluorescent material in the preparation of good the surface of the particles. (2) directly to the fluorescent marker substance or package containing the drugs into nanoparticles.

Isothiocyanates were fluorescein isothiocyanate fluorescent element (FITC) is tasted, yellow or orange to crystalline powder, soluble in water and alcohol solvent. Have two kinds of optical isomers, Ⅰ type in efficiency, stability and protein are more excellent adhesion, etc. For 389.4 FITC molecular weight, the maximum absorption wavelength for 490-495nm, maximum emission wavelength for 520-530nm, presents the bright green fluorescence. In the cold dark FITC dry can save years, is the most widely used fluorescent element. Its main advantage is sensitive to yellow eye, usually less than the green fluorescence sliced red specimens. With FITC markers of antibody], peptides, polysaccharide substances such as] has been widely used in various biological research. FITC have two points, including A in optical isomers efficiency, stability, and protein better ability, etc, in cold dark, dry place for many years, can save another sensitive to yellow-green due to human, usually less than the green fluorescence sliced specimen FITC become red, so the most widely used fluorescent element. With FITC markers of antibody, peptides, polysaccharide substances are widely used in all kinds of biological research. In recent years, the research on drug carrier, also often use fluorescent material. Fluorescent substance will introduce drug carrier methods are: (1) through chemical combination method of fluorescent substance made with polymer lateral-torsion coupling, after the lateral-torsion coupling into drug preparation of polymer particle or directly connected to fluorescent material surface preparation of good decoupling particles. (2) direct will mark or fluorescent substance into the bag contained nanoparticles drug. 异硫氰酸isothiocyanate角膜荧光素(牛)品、黄色和橙色到结晶粉末,易溶于水、醇溶剂。有两种类型的光学异构体,Ⅰ效率、稳定性和蛋白质更优异的附着力,等等。牛血清白蛋白分子量,为389.4的最大吸收波长为490 - 495nm、最大发射波长为520 - 530nm,呈现出明亮的绿色荧光。在寒冷的黑暗的牛,干可节省是目前应用最广泛的荧光素。它的主要优点是敏感的,黄色的眼,通常小于绿色荧光红标本。抗体标志物与牛,肽、多糖物质如]已广泛应用于各种生物学的研究。 牛有两个分,其中一个在光学异构体效率、稳定性、蛋白质和较强等,黑暗和寒冷、乾燥的地方很多年了,能拯救他人敏感,黄绿色,由于人类,通常小于绿色荧光切片样品变红牛,所以使用最广泛的荧光素。牛血清标记抗体,用多肽、多糖物质被广泛应用于各种各样的生物研究。 近年来的研究、药物载体,也经常用荧光材料。荧光物质将介绍药物载体的方法是:(1),通过化学方法组合的荧光物质与聚合物耦联后,药物制剂耦联到聚合物粒子或直接连接到荧光材料的表面准备好的解耦的粒子。(2)直接将标志或荧光物质进袋里装的纳米药物。 不知道能不能过关

The isothiocyanic acid fluorescein (fluorescein isothiocyanate, FITC) the sterling for the yellow or the orange yellow crystallization powder, easy to dissolve in the water and the ethyl alcohol resolver. Two kind of isomers, isomerⅠIn aspects and so on efficiency, stability and protein binding force is finer. The FITC molecular weight is 389.4, the biggest absorption light wave length is 490~495nm, the biggest emitting light wave length is 520~530nm, presents the bright Huang Lvse fluorescence. FITC in cold dark dry place may preserve many years, applies the most widespread fluorescein at present. Its principal advantage is the human eye is more sensitive to Huang Lvse, usually in section preparation's green fluorescence is short red. Each kind of immune body which marks with FITC], the multi-peptides, the polysaccharide] and so on materials have widely used in each living thing research. FITC has two kind of isometry bodies, isomer A in aspects and so on efficiency, stability, with protein combining capacity is better, in cold dark, dry place may preserve many years, because moreover the human eye is more sensitive to Huang Lvse, usually in section preparation's green fluorescence is short in red, therefore FITC becomes uses the most widespread fluorescein. Each kind of immune body which marks with FITC, the multi-peptides, materials and so on polysaccharide have widely used in each living thing research. in recent years regarding medicine carrier research, also often uses the fluorescent substances. Includes the fluorescent substances introduction medicine carrier's method: (1) causes the fluorescent substances and the polymer pair through chemical combination's method is joint, unites the pair the polymer prepares after again Cheng Zaiyao the particle or the fluorescent substances pair unites directly is preparing the good particle surface. (2) directly fluorescent substances or mark medicine Bao Zaijin nano particles.

For the yellow or orange FITC tasted crystalline powder, soluble in water and alcohol solvent. Have two kinds of optical isomers, Ⅰ type in efficiency, stability and protein are more excellent adhesion, etc. For 389.4 FITC molecular weight, the maximum absorption wavelength for 490-495nm, maximum emission wavelength for 520-530nm, presents the bright green fluorescence. In the cold dark FITC dry can save years, is the most widely used fluorescent element. Its main advantage is sensitive to yellow eye, usually less than the green fluorescence sliced red specimens. With FITC markers of antibody], peptides, polysaccharide substances such as] has been widely used in various biological research. FITC have two points, including A in optical isomers efficiency, stability, and protein better ability, etc, in cold dark, dry place for many years, can save another sensitive to yellow-green due to human, usually less than the green fluorescence sliced specimen FITC become red, so the most widely used fluorescent element. With FITC markers of antibody, peptides, polysaccharide substances are widely used in all kinds of biological research. In recent years, the research on drug carrier, also often use fluorescent material. Fluorescent substance will introduce drug carrier methods are: (1) through chemical combination method of fluorescent substance made with polymer lateral-torsion coupling, after the lateral-torsion coupling into drug preparation of polymer particle or directly connected to fluorescent material surface preparation of good decoupling particles. (2) direct will mark or fluorescent substance into the bag contained nanoparticles drug.
